---------------------------------------

Hi Dhruba, this will take some time as up to now my interaction with hdfs was based on javadoc
only. I will check what can I do.

> HDFS should expose a id that uniquely identifies a file. This helps in developing  applications
that work correctly even when files are moved from one directory to another. A typical use-case
is to make the Pluggable Block Placement Policy (HDFS-385) use fileid instead of filename.
